An average tooth pierces bone with how much root formation?

1/2
2/3
3/4
Full

The correct answer is: 2/3

An average tooth pierces bone with 2/3 root formation. The other options are incorrect because they either underestimate or overestimate the amount of root formation. Option A suggests only half of the root is formed, while option C suggests that the root is mostly formed with only one-quarter left to grow. Option D suggests that the root is fully formed, which is not necessarily the case and would mean the tooth could not continue to grow. Therefore, the most accurate and fitting option is B, with 2/3 root formation.
